PROBLEM DESCRIPTION
• This under-pan was
originally coated with
polyurethane. The
polyurethane was failing
due to inter-coat adhesion
issues and was coming off
in sheets.
• This was causing pump
blockages and leaving the
under-pan susceptible to
premature corrosion
issues.

SOLUTION
• ARC BX2 trowel-able
ceramic coating was
then coated at a
thickness of 6mm
directly under the inlet,
to assist with a greater
protection against
aggressive wear.

SOLUTION
• We then applied two
coatings of our ARC SD4i
ceramic reinforced
composite coating, at a
thickness of 400 Microns
each, giving a total
thickness of 800 Microns.
• The first coat was done in
blue and the second coat
in grey, assisting in future
wear indication.
